BukkitDev URL: http://dev.bukkit.org/server-mods/chunkmanager/ This plugin does some smart manipulation of the server internals to prevent the following chunk sending problems: Chunks are only sent while you are moving - one chunk per movement packet. Chunks beyond your viewing distance are still sent if you moved away from them before they were sent to you. Chunks will not be sent if you are receiving too many other types of packets (many entities nearby, for example). Chunks are sent with the chunks nearest to you being sent first. If you are moving fast, this will only load chunks behind you! With my plugin enabled, this changes to: Chunks are sent every 2 server ticks (10 chunks per second), whether you are moving or not, until you have all chunks near you. Chunks that are farther than 10 chunks away from you, are cancelled. Chunks will always go into the packet queue, even if many entities are nearby. Chunks are send based on the position you will be at in about a second, calculated with your current movement speed in mind. Works smoothly, even for insane speeds! Should be compatible with all other plugins, even plugins that mess around with chunks themselves, including spout! This plugin will gracefully fail if you are running an incompatible server and re-enable the vanilla chunk sending management, warning you in the server log about this. The latest beta version (0.4.3 at time of writing) can always be found here. And of course, source code is available on github. Note that this is in early development. It's stable, and your server will definately not crash with this plugin enabled, but there are no options and no permissions. It's either on or off for right now. Please report any problems you find, and suggestions for improvements! Compatibility: No known incompatibilities! Confirmed compatible with sometimes problematic plugins like Spout, Ore to Client Obfuscation, NoLagg (bergerkiller includes a modified version of my code in newer versions of NoLagg). Changelog: 0.4.3: Fixes compatibility with the latest RB (1.1-R3). 0.4.2: Fixes bug of random "holes" not loading until you stand in them. 0.4: Fixes all known bugs. (Cross-world teleporting being slow, player renaming breaking chunk sending, server reloading causing missing chunks) 0.3: Even more optimalisations, better handling of movement (fast movement especially - tested up to 200 blocks/s movement speed!), better handling of deleting far-away chunks. 0.2: Optimalisations and smaller code. No new functions, but works a lot faster and uses less memory. 0.1: First public release.
